I love Berezovsky's 1991 recording on Apex (not sure if it's still available). Pollini's, Cortot's and Sokolov's op.25 are favourites of mine too, but Berezovsky's are just something else. His technique is, as usual, flawless, but is hidden beneath the spontaneity and lyricism you can hear in his playing. It seems not so much of an "interpretation" as a natural and effortless rendering of something that already was - as though you're hearing the music itself rather than a pianist playing it. It's their Chopinesque nature that really gets me; obviously, no one can know how the man himself played them, but Berezovsky's just feel "right". They give me that irreplaceable feeling of being transported back to the time in which they were written, a kind of shivery nostalgia.
Pollini's are impressively virtuosic but a little too percussive. For me they sound like what they are - a modern-day recording of music composed in a very different time for a very different piano. Some may see this as a positive thing; I suppose it depends on what you look for in a recording. And Sokolov didn't record op.10 (or did he...?).
I'm sure others will disagree with my view completely, which is fair enough. But if the earth-shattering genius of the "Gavrilov is crap!", "No, you're crap!!" discussion above is anything to go by then I'd probably rather not hear about it. 
I do disagree with u about berezovsky, as much as I love him as a pianist for other recordings and performance. His Chopin etude is bounded to be one of the worst i have heard (not including rec like Rusnack), his approach is just so conservative and so repetitive. It sounds more like an old man trying to repeat himself. His recent Chopin, Chopin/Godowsky etude CD is much better, more elegant, more ideas, much more beautifully played.
I love Cortot Sokolov of course, Sokolov's live Op.25 is still setting benchmark of this set till this very day. Also Claudio Arrau's chopin etude recording, so very elegant, in an 'old master' kinda way, weird this recording hasn't been mentioned more often.
As weird as (and contrary belief to my SDC root), i do enjoy recordings such as Cortot and even the first rec of the complete set of Chopet by Backhaus (always like his).
Pollini's DG's recording is so fabricated, in both musical and recording sense.
His 14's yrs old Italian live radio broadcast is MUUCCHHHOOOO more superior, i really don't know what happened to him since then, it's all downhill from there it seems. (Kinda like Kissin)
Ashkenazy's early set sure is damn nice, probably one of my favorite recording of his by him.
John Browning is probably the best 'value for money' set u will ever get. balance on both musical and technical aspects. (U can imagine like Weissenberg playing complete Chopin etudes i guess)
of course Rafael Orocoz is always reliable. (the distribution of this recording is not though, unfortunately)
Murrary Perehia's chopin etude are getting mixed comments I see, but that is definately one of the CD that opened my eyes to the 'technical chopin'. And his 10/1 is actually very carefully planned in voicing. he must have practiced his ass off for that particular etude i felt.
o and of course my very favorite: SERGIO FIORENTINO
